We are in the process of Migrating from On-Premise Exchange and Sharepoint to Office 365 with Sharepoint.
We currently have an On-Premise Sharepoint 2013 Servers. We host Mail and Sharepoint for a few Companies, so the Sharepoint server is home to several Root level Sites:
Each root site is Managed by their own Administrators and the users are different for each site.
All users are part of the same Activity Directory Domain.
I have all of the domains Validated in Office 365 and mail is flowing to all of them.
I just dont see where I can Add a new Root level Domain and separate site for each of the existing sites I have.
